摘要： The present disclosure relates to a circuit breaker terminal box having a leakage current blocking function, in which a current leaking from both an input side and an output side of an earth leakage circuit breaker may be limited by expanding areas of a neutral line input terminal and a neutral line output terminal on both the input side and the output side of the earth leakage circuit breaker, and thus the risk of electric shock to the human body due to the leakage current can be minimized.

摘要： A leakage current detection and interruption (LCDI) device for a power cord includes a switch module that controls an electrical connection of first and second power supply lines between input and an output ends; a leakage current detection module, including first and second leakage current detection lines, which respectively cover the first and second power supply lines, and are respectively configured to detect leakage current signals on the first and second power supply lines and to generate self-test fault signals in response to the first and second leakage current detection lines having an open circuit; and a drive module which receives the first and/or second leakage current signal and the first and/or second self-test fault signal, and drives the switch module to disconnect the electrical connection in response to these signals. The LCDI device can individually detect leaks on the two power supply lines and open circuit on the two leakage current detection lines.

摘要： The present disclosure relates to an earth leakage circuit breaker and a method for controlling the same. The earth leakage breaker includes a zero-phase current detection unit for detecting a zero-phase current generated in a zero current transformer formed in three-phase electrical lines; a voltage detection unit for detecting a voltage from each of the two electrical lines; a trip unit for tripping contact points between the two electrical lines and a single-phase load when a trip signal is inputted; and a control unit which, when the zero-phase current is detected by the zero-phase current detection unit, detects an electrical line in which the voltage has dropped by a predetermined level or more, and generates and outputs the trip signal to the trip unit when the electrical line in which the voltage has dropped by a predetermined level or more exists.

摘要： A system is described herein, including an activation circuit configured to generate a signal indicative of an alarm condition. A residual current device trigger circuit is coupled to the activation circuit and a residual current device. The residual current device trigger circuit is configured to provide a simulated earth leakage current condition to trigger the residual current device on receiving the signal indicative of the alarm condition.

摘要： An electronic circuit breaker may include a monitoring circuit configured to monitor and respond to a power supply and/or detection circuit failure within the electronic circuit breaker. In some embodiments, the monitoring circuit may monitor a DC current received from a detection circuit within the electronic circuit breaker. A response to a power supply and/or detection circuit failure may include interrupting current flow between an electrical power source and an electrical circuit protected by the electronic circuit breaker. Methods of monitoring and responding to a power supply and/or detection circuit failure within an electronic circuit breaker are also provided, as are other aspects.

摘要： A supply system for supplying energy in an aircraft includes at least one electrical line including at least one core connectable to a pole of a current source, an electrically conductive shield, and a detection unit having at least two electrical inputs. The shield surrounds the at least one core under a distance and creates an intermediate space between the at least one core and the shield. At least one port of the detection unit is connected to the at least one core. At least another port of the detection unit is connected to at least one of the shield and the at least one core. The detection unit is adapted for detecting a differential current over the at least one core or an absolute current between the shield and a ground potential for generating a warning signal if a predetermined threshold value for the detected current value is exceeded.
